Once it is, open the Edge Bindings Settings pannel (Settings -> Input -> Edge Bindings). If you don’t find anything configured, then hit “Restore Default Bindigs” to set things back to normal. Done.

The other problem that seems to have reared its head is with the Enlightenment cursor, or rather the e17 cursor being affected by a bug in Xorg.

The easy fix is to disable the e17 cursor: Settings -> Look -> Mouse Cursor:
Change Cursor Settings to Use X Cursor.
(Some people have reported that disabling “Idle Cursor” also resets memory consumption back to normal).
